Hyena= a woman way past her sexual prime, easily identified by her national geographic tribal style saggy breasts and fried from over coloring hair. Habitat consists of bowling alleys, targets, doctors offices and the occasional coffee shop. The cackle is also a dead giveaway.
A woman who, in her prime, was considered a cougar. She has now aged too far to fit that classification, but not so far that you would turn down action from her.
